Equine assisted therapy uses horses to support human mental health and development. The welfare of therapy horses requires specific protection within these programmes.
Therapy horses provide significant benefit to human participants, but their welfare must not be subordinated to therapeutic outcomes. Horses forced into human contact against their behavioural signals experience chronic stress. Well-designed programmes include regular monitoring of horse stress signals, choice-based interaction where horses can disengage, adequate rest periods, and annual welfare assessments by equine behaviour specialists. The concept of consent in therapy animal programmes - allowing animals to choose participation - is gaining traction and represents the ethical frontier in this sector.
